In TravelLine WebPMS, you can see what changes have been made to a booking.
To do this, go to “Property management” > “Front desk”. In the tape chart, click on the booking you need. In the window opened, click on the “Edit” button.
In the booking details page, open the “Changes” tab.
There, you will see a table with all the changes made to the booking. You will see what setting has been changed, what it used to be, what it has become, date, time, and the user who made the change.
